Error: unexpected '}' in “}” if…print()…else…print() [duplicate]

问题

This question already has answers here:

if/else constructs inside and outside functions (2 answers)

Closed 5 years ago.

I WAS GIVEN ANSWER: THE if's closing BRACKET should be BEFORE ELSE not ABOVE.

This error had already been discussed here: Error: unexpected '}' in " }" and https://stackoverflow.com/questions/15303559/error-unexpected-in But they do not help me.

I run the code:

i <- 21
if(i==22){
 print(c("xxx"))
}
else{
 print(c("yyy"))
}

And get an error

else{ Error: unexpected 'else' in "else"
print(c("yyy")) [1] "yyy" } Error: unexpected '}' in "}"

I use Rstudio on Windows, quite new R version and Rstudio, but not sure where to check it

回答1:

Put the else after ifs bracket

i <- 21
if(i==22){
  print(c("xxx"))
}else{
  print(c("yyy"))
}

##[1] "yyy"

回答2:

This code will work in a function or when enclosed in braces, but not elsewhere because else is on a new line. See the duplicate question for more details.

Good practice is to put the else on the same line as the }. Then it will work for both.
